Abstract

A high strength, corrosion resistant Cr-Co-Ni base alloy for long-life service at 530° C. to 820° C. containing in % by weight about 23.5-25.5% Cr, 15.0-22.0% Co, 0.2-2.0% Al, 0.5-2.5% Ti, 0.5-2.5% Nb, up to 2.0% Mo, up to 1.0% Mn, 0.3-1.0% Si, up to 3.0% Fe, up to 0.3% Ta, up to 0.3% W, 0.005-0.08% C, 0.01-0.3 % Zr, 0.001-0.01% B, up to 0.05% rare earth as misch metal, 0.005-0.025% Mg plus optional Ca, balance Ni including trace additions and impurities. The alloy provides a combination of strength, ductility, stability, toughness and oxidation/sulfidation resistance so as to render the alloy range uniquely suitable for engineering applications where oxygen/sulfur-containing atmospheres are life limiting, in applications such as exhaust valves for diesel engines and in tubes for coal-fired steam boilers.
